There is a wrong behavior of the camera, it follows the weapon vertically when shooting and when moving the head with the X button and releasing it.
Naturally, when shooting, the head only vibrates slightly, the weapon moves and vibrates and the head remains still looking towards the target.
The precise form is:
When shooting, only the weapon moves (After rising backwards, it follows the camera.)
The weapon follows the camera when moving it by pressing and releasing the X button.
A slight vibration is added when shooting, without changing the direction of the camera.
